1. oil out of the syringe Do this to each cylinder and re install the plugs Do not turn the engine over again 3 Remove the valve covers and take the rocker arms off This closes any valves that may be open and keeps the moisture out of the cylinder Stops our good friend Rusty from working Keeps him on unemployment 4 Cover the carburetor inlet up so air cannot enter 5 Cover the exhaust outlet up so air cannot enter 6 If you cylinders are not painted spray a light coat of WD 40 on them to prevent winter rust But don t get carried away 7 Change the oil Don t let used oil sit in you engine all winter long You may consider adding the 4 quart so oil is up over the camshaft and lifter If you have a tail dragger raising the tail so the aircraft engine are level for the winter This covers more internal engine parts 8 If allowed by your Airport Authority you may install a 40W light bulb or two in the cowling under EGT and CHT Confusion There is lots of confusion about EGT and CHT I would advise all to go to these three web pages and read the facts about both http www avweb com news maint egt_and cht interpretation _198791 1 html http www sportaviationonline org sportaviation 201009 pg 95 pg95 http www foxvalleykart com gauges html Understanding egt cht will make your flying a lot more comfortable if you aren t worrying about your EGT in particular Both of these articles in that link are very good A2. The magnet ring on the 3 phase alternator is about 3 8 deeper that the old 20 and 22 amp alternators The Master Pattern had to be modified to accept the new alternator Will I still be able to get parts for the 22 amp alternator Yes we kept back a good supply of stators regulators rectifiers and have an adequate supply of magnet rings The only parts we have really replaced to date are a few stators and the regulator rectifiers Keeping the regulator rectifier cool and making sure they have a good ground is the secret to keeping them healthy Is there a weight difference between the new 35 amp 3 phase alternator and the old 22 amp single phase alternator Yes the new alternator with regulator weighs about 3 pounds more BEETLE FLYER 2010 WINTER 2010 NEW 12 x 4 x 5 Slick Tire amp Tube Many years ago we had a great 12 x 4 x 5 4 ply slick tire and tube available Dimensionally it is only 1 narrower than a standard aircraft 500 x 5 tire It disappeared many years ago While at the Small Engine Trade Show in Louisville KY this fall we found our old 12 x 4 x 5 4 ply slick tire to be available once again A pair of them 2 tires and 2 tubes runs 74 95 plus shipping Ethanol in Fuel We may be finding that the ethanol in the fuel we use in our aircraft may not be the best thing to burn in our VW conversions We had two cases this year of stuck valves in almost brand new engines Both engines were using eth
3. higher viscosity oil takes longer to warm up 1s harder to get pushed through the narrow opening in the lifter pushrod and rocker arm Camshaft lifter and valve train failure can all be attributed to thick oil A 60 weight oil for example is 100 thicker that a 30 weight oil at least by my math Oil has a number of jobs to do in an engine not just lubricate The oil s primary other job of course is to collect heat transport it to the oil cooler and shed the heat A high viscosity oil will produce a higher oil pressure but at the expense of a higher oil temperature The VW service manual lists the following for a minimum oil pressure Oil pressure for SAE 30 only at an oil temperature of 158 F at 2500 rpm results in 28 psi for a Type 1 engine It does not list a max at any other rpm nor does it list a minimum at idle 4 GREAT PLAINS BEETLE FLYER WINTER 2010 Extended Storage that will keep your engine healthy 1 For an installed running engine consider fogging it Simply use a spray bottle of lightweight oil and spray the carburetor with the engine running at about 1200 rpm and choke the engine down so it quits Yes the engine should be at operating temps and if needed remove the prop to do this 2 For an non installed non running engine remove the top plugs and using a syringe put an ounce or 2 of oil in the cylinder I use a small tube on the end so I can move it around a little when pushing the

Nn en ed Pee ed a N NO A m r Great Plains Aircra supply Co Happy Holidays Hoping that 2010 was a great year for each of you And we hope that your airplanes are getting close to flight WINTER 201 0 NEW 35 Amp 3 Phase Alternator We thank each of you for being our customers and another successful year at Great Plains Hope that 2011 is full of great flying days This next year will be our 29th year that s very hard to believe of seling VW conversions and parts for Sport Aircraft We have exhibited at Sun and Fun and Oshkosh now Air Venture since 1984 Plus we have been conducting many forums and workshops at both of these air shows What s in the Beetle Flyer The new 35 Amp 3 phase alternator brings many benefits to our VW conversions First all the amps are in by 1500 rpm The magnet ring has a 006 stainless steel ring pressed around the magnets so they can never come loose and wedge between another magnet and the stator And the best benefit is that 3 phase does not produce any electrical noise for your radio This fact is not so important for metal or steel tube airframes that have a good ground 1 e the whole airframe But for wood and plastic aircraft it can make a tremendous difference in noise especially if you using one of the less expensive aircraft radios To answer a few questions Will my older Diehl Case accept the new 35 amp 3 phase alternator No it won t
6. anol The valves stuck as early as 2 hours on one engine and at about 5 hours of operation on the other While it is not by any means a scientific test Just be f W overly cautious if using ethanol laced auto fuel This el might be a good discussion topic on some of the VW yahoo sites and at Sonerai net to see if any other VW flyers that are using ethanol and what if any issues they have had I would be especially cautious if using a POSA type carburetor due to the increased possibility of vapor lock Sun amp Fun 2011 Sun and Fun is earlier this year March 29 to April 3 We will again host our Build a VW Engine in the Engine workshop area This is a four day workshop that only takes 1 to 2 hours per day starting at 11 00 A M Day 1 is VW Aviation History engine selection and what parts to use and not to use Day 2 is assembly of the short block Day 3 is completing the engine assembly and adding the accessories _ Day 41s fuel carbs and cooling No need to sign up just show up We have ran this program at Sun and Fun for about the last 10 years and at Oshkosh for the last 5 years or so and have had literally 100 s of graduates Well no one got a diploma actually But we think it has made flying a VW safer at any rate 2 BEETLE FLYER 2010 WINTER 2010 Easy Eagle I takes Flight in Nebraska Back in 2005 I started building an Easy Eagle I Unfortunately I would rather fly than build and

8. nd on the CHT side I would only add that if you take your CHT reading on a VW under the plug which is the hottest spot the max is usually about 450 F If you are taking the reading from under a cylinder head stud washer behind the intake manifold the maximum CHT should be about 325 F
